Amazon will account for 39.5 percent of all U.S. retail e-commerce sales in 2022, or nearly $2 in $5 spent online, according to a recent eMarketer feature. Altogether, the next 14 biggest digital retailers will make up just 31.0 percent, with the remaining 29.5 percent of the e-commerce pie going to everybody else.

It seems the competition just can’t keep up. This year, Amazon will pocket more than $400 billion of the country’s roughly $1 trillion in e-commerce sales. The retail giant will also rake in more than five times the digital sales of its closest rival, Walmart Inc., and see those sales grow by 14.6 percent, faster than the overall U.S. e-commerce market, which will expand by 14.1 percent.
